How are lactic acid fermentation and aerobic respiration different?

1 answer:

7 0

Lactic acid fermentation occurs as an alternative to that of aerobic respiration, this occurs in cases where oxygen levels or concentrations within the cells are very low and as a result, is not available for the acceptance of electrons as the final electron acceptor. The cells undergo this process, where essentially, rather mr than using oxygen as the final electron acceptor after producing ATP. NAD+ I believe is able to accept electrons and thus we can produce ATP, again. Glycolysis occurs but rather than moving on to the next stage, Pyruvate molecules are ultimately converted to lactic acid which releases ATP, the extra electrons would go to NAD+ which is needed to keep the reactions going.

In what phase of mitosis do the centrioles separate?

Olegator [25]

Answer:

Prophase

Explanation:

During prophase, chromatin condenses into chromosomes, and the nuclear envelope, or membrane, breaks down. In animal cells, the centrioles near the nucleus begin to separate and move to opposite poles (sides) of the cell.

VikaD [51]

<h3>Answer:</h3>

The Correct answer is... C. Protists are a catch-all group for eukaryotes that aren't plants, fungi, or animals.

<h3>Explanation:</h3>

Let's break it down!

~~~

A. Protists are all heterotrophic.

The given statement in answer choice A. is (partially correct) FALSE.

The following statement is TRUE... The protist is classified as either autotrophs or heterotrophs.

~~~

B. Protists can't live in freshwater.

The given statement in answer choice B. is also FALSE.

TRUE... Nearly all protists exist in some type of aquatic environment, including freshwater.

~~~

C. Protists are a catch-all group for eukaryotes that aren't plants, fungi, or animals.

The given statement in answer choice C. is CORRECT!

TRUE... As the catchall term for eukaryotic organisms that are not animals, plants, fungi, or any single phylogenetically related group, it is not surprising that few characteristics are common to all protists.

~~~

D. Protists are all parasitic.

The given statement in answer choice D. is (partially correct) FALSE.

TRUE... Many protists are pathogenic parasites that must infect other organisms to survive and propagate.

~~~

Therefore, the correct answer choice is C.
